Kris Maglione e930b89c34 Bug 1514594: Part 3 - Change ChromeUtils.import API.
***
Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8

This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:

  ChromeUtils.import("resource://gre/modules/Services.jsm");

is approximately the same as the following, in the new model:

  var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");

Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

Bug 1514594: Part 3b - Mass rewrite all JS code to use the new ChromeUtils.import API. rs=Gijs
